I have a number of exposed black and white film rolls (Tri-X and Plus-X), all over 10 years old, some approaching 30. I am looking for a lab to (only) develop this film using the best available techniques to optimize the images given the films' age. Several labs came up in searches on the Web and on this site which specialize in this sort of service: Bluefire Antique Film Processing (Calgary, Canada), linked to Adox Fotowerk, Inc.; Dwain Coufal Photography (Temple, TX); Rocky Mountain Film Laboratory (Aurora, CO); Film Rescue International (Fortuna, ND). I would appreciate feedback on these outfits or any others which perform this sort of work in order to help make an informed decision as to which one(s) would do the best job, and whether there are any which are to be avoided. Thanks in advance for the input.
